摘要： A method of synchronising a generator drive with an alternating current electrical network. A generator is driven by a hydraulic motor having a hydraulic input coupled to a source of pressurised hydraulic fluid and one or more working chambers of cyclically varying volume for receiving and depressurising discrete portions of received hydraulic fluid, the volume of pressurised hydraulic fluid received by each working chamber being selectable for each cycle of working chamber volume, the generator drive comprising a controller which selects the volume of the pressurised hydraulic fluid which is received by each working chamber on each cycle of working chamber volume to thereby drive the generator. The controller controls the rate of receipt and depressurisation of hydraulic fluid by the hydraulic motor to match the frequency, and then the phase, of the output from the electrical generator with an electrical network. The procedure enables synchronisation to take place rapidly. The motor can be part of the hydraulic transmission of a wind turbine generator or other renewable energy generation device and receive pressurised fluid from a hydraulic pump, driven by a rotor, through a pressurised fluid line. When controlling the displacement of the hydraulic motor, the pressure variations in the pressurised fluid line are rejected. Motor displacement is also regulated to avoid underpressure in the pressurised fluid line. During synchronisation the pitch of the turbine blades and the displacement of the hydraulic pump are also regulated. The renewable energy generation device can therefore be started up efficiently and reliably.

摘要： A wind turbine generator (100), or other energy extraction device, has a hydraulic circuit comprising a hydraulic pump (129) driven by a rotating shaft (125) and a hydraulic motor (131) driving an electricity generator (157), or other load. A high pressure manifold (133) extending between the pump and motor is in communication with an accumulator (145, 147, 149). A controller receives a control signal and regulates the displacement of working fluid by the hydraulic pump and the hydraulic motor relative to each other. Thus, power input through the rotating shaft and output to the load can be decoupled for at least a period of time and the energy output of energy extraction device can be varied, for example to smooth the total power output to an electricity grid (101), without compromising power input. A group of energy extraction devices can be controlled in concert to maximise power input while providing smooth power output. Individual electricity generators in different energy extraction devices can be switched on and off in concert to provide smooth power output while benefiting from the reduced energy losses that can be obtained by switching off electricity generators where possible.

摘要： An energy extraction device and method for extracting energy from a fluctuating energy flow from a renewable energy source. A hydraulic pump is driven by a rotating shaft, driven in turn by a renewable energy source. A hydraulic motor drives a load and a high pressure manifold communicates between the pump, motor and an elastically deformable fluid retaining body. The hydraulic pump and hydraulic motor comprise working chambers displacing a volume of working fluid selectable on each cycle of working chamber volume by the control of electronic valves. The pressure in the high pressure manifold is measured and the net rate of displacement of working fluid by the hydraulic pump is selected responsive thereto to regulate the torgue applied to the said rotating shaft. The net rate of displacement of working fluid by the hydraulic motor is selected to smooth the energy flow to the load. The net rate of displacement of working fluid by the hydraulic motor is selected to cause the pressure within the high pressure manifold to tend towards an optimum. The optimum is variable and can be selected to optimise the efficiency of power transmission from the rotating shaft to the load or to increase the longevity of the energy extraction device.

摘要： A fluid-working machine has a working chamber of cyclically varying volume, high and low pressure manifolds, and high and low pressure valves for regulating the flow of fluid between the working chamber and the high and low pressure manifolds respectively. A controller actively controls at least one said valve to determine the net displacement of working fluid of the working chamber on a cycle by cycle basis. At least one said valve is a variable timing valve and the controller causes the valve to open or close at a time determined taking into account one or more properties of the performance of the fluid working machine measured during an earlier cycle of working chamber volume. Properties of the opening or closing of a monitored valve may be taken into account. The variably timed valve may therefore be opened or closed at an optimum time to achieve efficient and reliable operation of the fluid- working machine. The magnitude of the opening or closing force applied to a valve member may also be varied.

摘要： A hydraulic transmission comprises a variable displacement hydraulic pump and a variable displacement hydraulic motor, connected by high and low pressure lines. One of the hydraulic pump and the hydraulic motor has a discontinuous range of displacements. The other has a continuous range of displacements. In order to allow a continuous range of input and output torques, despite the discontinuous range of displacements, the pressure in a high pressure line is varied. This enables a hydraulic pump or motor which has a discontinuous range of displacements but other technical advantages, such as reduced torque ripple, to be employed without losing fine control of input and output torque. The hydraulic transmission is useful for a wind turbine where the turbine drives a hydraulic pump operated with a discontinuous range of displacements.

摘要： A wind turbine generator (100), or other energy extraction device, has a hydraulic circuit comprising a hydraulic pump (129) driven by a rotating shaft (125) and a hydraulic motor (131) driving an electricity generator (157). When the electricity generator is switched off, it executes one or more pumping cycles to pressurise the high pressure manifold and therefore recover angular kinetic energy from the electricity generator rotor which can later be used to reaccelerate the electricity generator rotor to the correct operating speed for an electricity grid (101). Overall energy efficiency is increased and the minimum operating high pressure manifold pressure may be reduced as a result.

摘要： It is intended to provide a power generating apparatus of renewable energy type in which the synchronous generator can be connected to the gird without the frequency converting circuit and which is capable of improving efficiency during low-load operation and of avoiding missing opportunities of power generation due to failure of the generator. A power generating apparatus of renewable energy type 1 may include a rotating shaft 8 rotated by the renewable energy received via a blade 4, a hydraulic pump 12 driven by the rotating shaft 8 to generate pressurized oil, hydraulic motors 14 k driven by the pressurized oil, and synchronous generators 20 k connected to a grid 50 without an intervening frequency-conversion circuit and respectively coupled to the hydraulic motors 14 k . The displacements of the hydraulic motors 14 k are adjusted independently by a motor control unit 48. A synchronizer 120 supplies a command value of the displacement of each hydraulic motor 14 k to the motor control unit 48 so that before the synchronous generators 20 k are connected to the grid, a frequency and a phase of a terminal voltage of each synchronous generator 20 k are synchronized with the grid 50.
